PERLEY HALE, OF SAN DIEGO, CALIFQRNIA.

TIDE-MOTOR.

To all whom it may concern:

Be it known that I, PEBLEY HALE, a eitizen of the Uited States, and a resident 'ot' the city of San Diego, countyjof San Diego, and Stat-e of California, .have invented certain new and useful Improvements in Tide- Motors, of which the 'following is a specification. i

My invention relates to improvements in tide motors and -"hasfor its-object the pro' vision of an improved tide motor of simple construction and e'liicient 'sin i operation.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed. i

The invention will be best understood' by reference to the accompanying drawings forming a part of this specification, and in which, f I

Figure 1 is a top plan view of a. tide motor embodying my invention, Fig. 2, a section taken on line -m of Fig. 1, Fig. 3, a small detail view of a well and float employed for automatically controlling the operation of the device, and Fig. 4, a detail view of circuit breakers employed in automatically controlling the operation of the device..

The preferred form of construction as illustrated in the drawings comprises a power reservoir 1 having one 'or more automatically opening inlet valves 2 which are arranged to open automatically to permit entry of water from the sea and close automatically to preventescape of pater from reservoir 1. One or more turJine water wheels 3 of any usual 4or desired construction, are arranged at the bottom of the reservoir 1 and are adapted to be operated by water escaping from said reservoir, as will be readily understood by those skilled in the art. Each of the Water Wheels is arranged to operate a vertically disposed shaft 4i which extends above the top of reservoir and is adapted to operaie as .a suitable means for transmitting power from the motor. A rod 8 is extended downwardly from the top of reservoir 1 andis connected to operate the ordinary controlling means or valves of each of the Water Wheelsl as will be readily Specification of Letters Patent.

and the other one closed. Shaft 16'is driven Patented oet. 21,1913.

from said Waste reservoir into said flume.' i. At their outer ends flunies Q are provided I with swinging v alves 12 adapted to permit escape of water from the corresponding fiume 9 into the open sea but prevent entry.. of water `from the sea to the corresponding fiumes. x' i Operating cables 13 and 14 are connected i with valves 10 and 12respectively and are g5' extended upwardly through suitable wells, 15 formed in reservoir 1 and are wound at their upper ends upon an operating shaftv 16. By this arrangement it will be observed that upon rotating shaft 16 in one direction one of the-valves 10 or 12 Will be closed and the other permitted to open, 'and that when shaft 16is rotated in the reverse direction the opposite valve will be permitted to open 76 'from an electric motor 17 by means of a suitable belt as indicated, and the operation of motor 17 is controlled by means of a spring held switch 18 which is adapted to be shifted to `two different positions to reverse the vdirection of currents through said motor andthus reverse the'A direction as "will be readily understo'od by those skilled in the art. Bridgingcircuits I and II are connected lwith the 35 circuits onmotor 17 and also with suitable circuit breakers 19 arranged in one of the Wells 15 as indicated. Cables 13 and 14 are f passed through the ends of circuit breakers 19 and are provided with knots or stops 20 i0 'and 21 adapted to engageeaid circuit breakers as indicated in- Figfli. The arrangement is such that when cable 14 is wound upon shaft 16 it closes valve 12, and knot 2],4 engages the corresponding circuit breakerjllly 19 and breaks bridgmg circuit II, thus-interi rupting the operation of `motor 17 and consequently stopping the action of shaft 16. Likewise when cable 131s wrapped upon lshaft 16 knot 20 engages the corresponding 100 'that the sea level is below valve 12, switch 11u 18 is operated by the weight of float 2310 shift switch lever 18'to.the position indiv eatedin Fig, 1 which causes operation of motor 17 to close valvewlQ ,and permit automatic opening of valve 12. This permits the discharge from water Wheels 3 to pass di- 5 rectly out to the sea and thus prevents oper- ,atiOn of the waterin5 reservoir `1 a ainst a `"head in reservoir 11. When the tite rises :'*entry'offwater to reservoir 11 when the tide "rises. By this arrangement it will be obf. T jfsei'ved' that Waste reservoir 11 will be autolmati'cally 'drained at each low tide. Apro- "tec`ting"apron 28is arranged over the exflfposed sideof the'construction land provided with suitablev openings 29 adapted to per- `viit passageof the'sea Water thereto, said apronfbei'ng designed for protection of the 30"-"parts from the force of waves and also to 'direetthe waves intothe open top of reseri fvoirL 1v thus increasing lthe height of water ftherein above -thatfof ebb tide.

The different reservoirs, lumes and apron may be made of any suitable or desirable material'but 'I prefer the use of reinforced oncrete, ,which will be found l highly eiicient -n use. A 'J 4llVhile I-fhave illustrated and described the *preferred form, of construction for carrying my invention: into effect, this is capable of y l A'lfvariation' and modification `Without departingffroin lthe spirit ofthe invention. I, therefore, do notwish to be limited to the ,precise details of construction set forth,- but Qdelsire to avail Inyselfof such variations and d 'ffmodifleations as come Within the'scope of if? thevappended claims.`

'Havingydeseribedi my. invention what I Ycla'im'as new, and desire to secure by Letters y[Patent is? A y 7 y 1. A tide motori 'comprising a power res- ''ervoir; power developin means arranged to be operated by water rom said reservoir; 551,'a waste reservoir; and means for directing f the discharge yfromv saidpower developing n vmeans into said vwaste reservoir or into 'the open sea, substantially as described.

ff 2, A ftideumotorl comprising a power res- I ervoir; power developing means arranged to be operated by water from said reservoir; a waste reservoir; means for directing the discharge from said power developing means into said waste reservoir or into the o pen sea; and means automatically controlled by the sea level arranged to control said discharging means, substantially as described..A

3. A tide motor comprising a power reservoir; power developing means arranged`to be operated by water from said reservoir; a waste reservoir; means for directing the discharge from said power developing means into said wastereservoir or into the open sea; and iioat operating means automatically controlled by the sea level. arranged to control said discharging means, substantially as described.

4. A tide motor comprising a 'power reservoir; an automatic valve for said reservoir arranged to ermit entry of water thereto but prevent its escape; a water Wheel arranged to be operated by water from said reservoir; a waste reservoir; a flume leading from said reservoir' into said open sea and arranged to receive the discharge from said water Wheel; a valve at each end of said flume; means for opening and closing said valves; a second fiume leading from said Waste reservoir to the open sea; and an automatically operating valve for said second flume adapted to permit escape of water to the sea but prevent entry of water to said Waste reservoir, substantially as described.

5. A tide motor comprising a power reser voir; an automatic valve for said reservoir arranged to ermit entryof Water thereto but prevent its escape; a water wheel arlranged to be operated bywater from saidy reservoir; a wasteA reservoir; a iiume leadu ing from said waste 'reservoir to the open sea and arranged to receive the discharge from said water Wheel; a valve .at each' end of said flume; float controlled electricalmeans for opening and closing said valves; aA second fiume leading from said waste reservoir to the open sea; and an automatically opening varlve for said second flume adapted to per mit escape of Water to the sea but` prevent entry of Water to said Waste reservoir, substantially as described.

In testimony whereof I have signed my name to this specification in the presence oi' tWo subscribing witnesses.
